6.2 Electrical Wiring Connection
(1) Perform the electrical wiring work for the CH-Boxes. Select the wire size according to the table below.
(2) Pay attention to the marks on the terminal block when connecting wires for CH-Box and I.U./O.U.
Refer to “Example of Electrical Wiring” for the wiring connection on the next page.
Table 6.1 Electrical Data and Recommended Wiring, Breaker Size
NOTES:
1) Follow local codes and regulations when selecting field wires.
2) The wire sizes marked with *1 in the above table are selected at the maximum current of the unit according to the
European Standard, EN60 335-1. Use the wires which are not lighter than the ordinary tough rubber sheathed flexible
cord (code designation H05RN-F) or ordinary polychloroprene sheathed flexible cord (code designation H05RN-F).
3) The wire sizes marked with *2 in the above table are selected at the maximum current of the unit according to the
wire, MLFC (Flame Retardant Polyflex Wire) manufactured by Hitachi Cable Ltd., Japan.
4) Use a shielded cable for the transmitting circuit and connect it to ground.
5) In the case that power cables are connected in series, add each unit maximum current and select wires below.
